RELATED APPLICATIONS

The present application claims the benefit of U.S. Provisional PatentApplication No. 60/665,165 filed on Mar. 25, 2005 and PCT/US2006/011271filed on Mar. 27, 2006.

BACKGROUND OF THE INVENTION

The development of a new pharmaceutical agent requires carefuloptimization of the chemical and biological properties of a leadcompound. For example, a successful drug candidate must be safe andeffective for its intended use. Further, the compound must possessdesired pharmacokinetic and pharmacodynamic profiles. This arduousdevelopment process usually requires extensive experimentation. In manycases, the process for determining the optimal compound can oftenrequire preparation of thousands of structurally similar compounds.

Among the properties that can limit the utility of a potentialpharmaceutical agent the degree to which the compound is complexed toproteins in vivo. If a high percentage of the compound present in vivois non-specifically bound, for example by components of blood and bloodplasma, this leaves only a very small amount of free compound availableto tissue to perform its therapeutic function. Thus, binding of thecompound to various proteins and other plasma components may require anunacceptably large dosage of compound to achieve the desired therapeuticeffect.

Traditional approaches have sought to alter pharmacokinetic properties.

The Rho-associated kinase is a key intracellular regulator ofcytoskeletal dynamics and cell motility. Rho-kinase regulates a numberof downstream targets of RhoA through phosphorylation, including, forexample, myosin light chain, the myosin light chain phosphatase bindingsubunit and LIM-kinase 2. In smooth muscle cells Rho-kinase mediatescalcium sensitization and smooth muscle contraction. Inhibition ofRho-kinase blocks 5-HT and phenylephrine agonist induced musclecontraction. When introduced into non-smooth muscle cells, Rho kinaseinduces stress fiber formation and is required for the cellulartransformation mediated by RhoA. Rho kinase participates in a variety ofcellular processes, including but not limited to Na/H exchange transportsystem activation, stress fiber formation, adducin activation. Rhokinase is involved in physiological processes such as vasoconstriction,bronchial smooth muscle constriction, vascular smooth muscle andendothelial cell proliferation, platelet aggregation, and others.

Inhibition of Rho-kinase activity in animal models has demonstrated anumber of benefits of Rho-kinase inhibitors for the treatment of humandiseases. These include models of cardiovascular diseases such ashypertension, atherosclerosis, restenosis, cardiac hypertrophy, ocularhypertension, cerebral ischemia, cerebral vasospasm, penile erectiledysfunction, central nervous system disorders such as neuronaldegeneration and spinal cord injury, and in neoplasias where inhibitionof Rho-kinase activity has been shown to inhibit tumor cell growth andmetastasis, angiogenesis, arterial thrombotic disorders such as plateletaggregation and leukocyte aggregation, asthma, regulation ofintraoccular pressure, and bone resorption. The inhibition of Rho-kinaseactivity in patients has benefits for controlling cerebral vasospasmsand ischemia following subarachnoid hemorrhage.

In mammals, Rho-kinase consists of two isoforms, ROCK1 (ROCKβ;p160-ROCK) and ROCK2 (ROCKα). ROCK1 and ROCK2 are differentiallyexpressed and regulated in specific tissues. For example, ROCK1 isubiquitously expressed at relatively high levels, whereas ROCK2 ispreferentially expressed in cardiac and brain tissues and in adevelopmental stage specific manner. ROCK1 is a substrate for cleavageby caspase-3 during apoptosis, whereas ROCK2 is not. Smooth musclespecific basic calponin is phosphorylated only by ROCK2.

Further, the physiological roles of the proteins appear to be distinct.For example, a recent study comparing the ROCK1/+ haploinsufficient micewith wild type littermates indicated that ROCK1 is critical for thedevelopment of cardiac fibrosis, but not hypertrophy, in response tovarious pathological conditions and suggest that signaling pathwaysleading to the hypertrophic and profibrotic response of the heart aredistinct. However, the lack of inhibitors specific for ROCK1 or ROCK2has impeded their respective roles to otherwise be distinguished.

Accordingly, there is a need for improved ROCK specific kinaseinhibitors, including kinase inhibitors that specifically inhibit ROCK1or ROCK2.

The compound (IV) is aromatized to the chloroquinazoline (V) bytreatment with thionyl chloride (SOCl₂) with catalytic dimethylformamide(DMF). The reaction mixture is heated to reflux for 1-6 hours preferably4 hours. Alternatively phosphorous oxy trichloride (POCl₃) or oxalylchloride can be used instead of SOCl₂ to effect this transformation.

The chloroquinazoline is reacted with an appropriately protected 5-aminoindazole (VI) to give the amino quinazoline (VII). The reaction iscarried out in iso-propanol at 95° C. for a reaction time of 30 minutesto 2 hours.

The protected indazole (VI) can be prepared as depicted in Scheme B.5-Nitro-indazole is appropriately protected via methods known to thoseskilled in the art, preferably with a tert-butoxy carbonyl group. Thenitro group is the reduced to the amino group via hydrogenation using ametal catalyst such as Pd/C in an inert solvent such as methanol (MeOH),1,2 dimethoxethane (DME), ethanol (EtOH) or acetic acid (AcOH) or acombination of solvents preferably in a combination of MeOH and DME. Thereaction can be carried out under balloon pressure or under a pressureof 20-50 pounds per square inch (p.s.i.).

Compounds of formula (XII) can be synthesized as depicted in scheme C.Compound (VII) can undergo selective deprotection of the O-protectinggroup functionality to give compound (VII) where X═OH. This can be doneby a variety of methods, which are well known to those skilled in theart.

The modification of protein binding is based on surface technology, i.e.the preparation and screening of surfaces for their ability to resistadsorption of proteins from solution. Surfaces which are resistant toadsorption of proteins from solution are known to one of skill in theart as “protein resistant” surfaces. Functional groups may be screenedto identify the group(s) present in protein resistant surfaces, asdescribed in e.g., Chapman et al. Surveying for Surfaces that Resist theAdsorption of Proteins, J. Am. Chem. Soc. 2000, 122:8303-8304; Ostuni etal. A Survey of Structure-Property Relationships of Surfaces that Resistthe Adsorption of Protein, Langmuir 2001, 17:5605-5620; Holmlin, et al.Zwitterionic SAMs that Resist Nonspecific Adsorption of Protein fromAqueous Buffer, Langmuir 2001, 17:2841-2850; and Ostuni et al.Self-Assembled Monolayers that Resist the Adsorption of Proteins and theAdhesion of Bacterial and Mammalian Cells, Langmuir 2001, 17:6336-6343.

In general, protein binding is assessed by measuring the capacity ofmolecules of the invention to bind to one or more human serum componentsor mimics thereof. In one embodiment, suitable functional residues maybe identified by screening of surfaces comprising such residues fortheir ability to resist adsorption of serum components, including, butnot limited to serum proteins, and preferably human serum proteins.Candidate residues can be screened directly by attaching them to a solidsupport and testing the support for protein resistance. Alternatively,candidate residues are incorporated into, or linked to molecules ofpharmaceutical interest. Such compounds may be synthesized on a solidsupport, or bound to a solid support after synthesis. In a non-limitingexample of a direct binding assay, immobilized candidate functionalresidues or molecules incorporating such residues are tested for theirability to bind serum components. The serum components can be labeledwith a signaling moiety for detection, or a labeled secondary reagentthat binds to such serum components can be used.

Surfaces which are resistant to adsorption of proteins from solution areknown as “protein resistant” surfaces. Functional groups may be screenedto identify the group(s) present in protein resistant surfaces, asdescribed in e.g., Chapman et al. Surveying for Surfaces that Resist theAdsorption of Proteins, J.

Upon identification of a functional residue which provides such proteinresistance, one of skill in the art will readily determine a suitablechemical skeleton or backbone of a known biologically or chemicallyactive compound to which the functional residue may be attached byeither substitution of functional group of the active compound or byreplacement of a nonessential functional group of the active compound.For example, as discussed above, the presence of a piperazine group on acompound will indicate that such group may be either replaced orsubstituted with an functional residue. One of skill in the art, e.g. amedicinal chemist, will recognize other suitable groups on known activecompounds which may be replaced or substituted with at least onefunctional residue. Accordingly, a combinatorial library of compounds,may be generated as described infra, wherein the compounds are modifiedcompounds comprising a conjugate of an active site of the compound (anessential backbone of a compound having a particular desired activity),e.g. compound A and at least one functional residue attached thereto,wherein each conjugate has a different functional residue attachedthereto, e.g. residues having formula C, wherein each R group isselected from the various groups described herein. Accordingly, alibrary may be used to screen a plurality of different functionalresidues for improved pharmacokinetic and/or pharmacodynamic propertiesincluding non-specific protein binding of the modified compound.

In preferred embodiments, the solid support itself is chosen or modifiedto minimize its interaction with the serum components. Examples of suchsupports and assay systems are described in International Application WO02/48676, WO 03/12392, WO 03/18854, WO 03/54515, herein incorporated byreference. Alternatively, the molecules of the invention may be mixedwith one or more serum components in liquid phase, and the amount ofunbound molecules determined.

A direct binding analysis can also be preformed in liquid phase. Forexample, test compounds can be mixed with one or more serum componentsin liquid phase, and the unbound molecules determined.

In an example of a preferred embodiment, molecules having reducedprotein binding are identified as follows: a self-assembled monolayer ofthiol molecules terminated with anhydride groups is formed at a goldsurface. A set of small molecules with amine groups at one end, andgroups that are designed to resist binding to albumin, for example, atthe other end are then attached to the surface via reaction between theamine and anhydride. The set of molecules are spotted onto spatiallydistinct regions on the gold surface to create an array of moleculesthat might resist protein binding. This array is then exposed to asolution containing albumin that is fluorescently labeled. After asuitable incubation period, the gold surface is washed and scanned on afluorescent scanner. The immobilized chemical groups that bound toalbumin will be identified by the presence of a fluorescent signal;groups that resist albumin binding will have low fluorescence in thatpart of the array. If a fluorescent protein is not available thenantibodies against the protein of interest in combination withfluorescent secondary antibodies can be used to detect protein bindingto the chemical groups. If an antibody is not available then a labelessdetection method such as surface plasmon resonance (SPR) or MALDI massspectrometry can be used to identify the presence of the protein atindividual elements in the array. SPR also has the advantage ofproviding kinetic information on the binding of protein to the chemicalgroups.

The use of this system is not limited to albumin; any protein ofpharmacokinetic interest can be tested for binding potential. Forexample, blood proteins that bind small molecules, such as α-acidglycoprotein (AAG, AGP) and lipoproteins, could be exposed to the arrayand protein binding detected.

In an embodiment of the invention, chemical groups can be identifiedthat resist binding to P-glycoprotein (PGP) and therefore have thepotential to reduce efflux when appended to a small moleculetherapeutic. This is particularly important for development ofanti-cancer drugs provide effective treatment where multiple drugresistance (MDR) has developed.

The method could also be used to identify chemical groups that resistbinding to proteins such as thrombin, anti-thrombin, and Factor Xa andtherefore have the potential to control coagulation.

This method would also be useful for identifying groups that improvetherapeutics that are designed as supplemental or replacement therapieswhere protein binding and PK properties are very important, e.g.,hormones and their binding proteins, and steroids and their bindingproteins such as testosterone and sex hormone binding globulin (SHBG).

The following describes a surface-based method for identifying groupsthat can improve the solubility of small molecules. A self-assembledmonolayer of thiol molecules terminated with maleimide groups is formedat a gold surface. A set of small molecules with thiol groups at oneend, and groups that are hydrophilic at the other end are then attachedto the surface via reaction between the thiol and maleimide. The set ofmolecules are spotted onto spatially distinct regions on the goldsurface to create an array of molecules that might increase thesolubility of a small molecule. Droplets of both polar (e.g., water) andhydrophobic (e.g., octanol) liquids are then placed onto each element ofthe array. The contact angles of the two liquids on each element arethen measured at each element of the array using a goniometer.Alternatively, the wettability of a particular liquid at a surfacepresenting a chemical group can be determined by measuring the area ofthe surface covered by a droplet when viewed from above (high contactangle will yield droplets of small area; low contact angles covergreater areas). The contact angle of a liquid on a surface presenting achemical group is inversely proportional to the miscibility of thatchemical group with that liquid (solvent). For example, a chemical groupfor which water has a high contact angle when it is presented at thesurface, such as methyl (CH₃), has low miscibility with water, i.e., itwill tend to reduce the solubility of a small molecule. Conversely, achemical group for which water has a low contact angle when it ispresented at the surface, such as carboxyl (COOH), has high miscibilitywith water, i.e., it will tend to increase the solubility of a smallmolecule. Sets of chemical groups can therefore be screened rapidlyusing contact angles on surfaces to identify groups that improvesolubility or reduce hydrophilicity. This approach can be used toevaluate the effect on solubility of chemical groups used according tothe invention.

A common parameter for the ability of a small molecule to cross thelipid membrane of a cell is logP where P is the partition coefficient ofthe compound between octanol and water. The relative contact angle of asurface presenting chemical groups for octanol and water thereforeoffers a rapid, empirical method for ranking large sets of chemicalgroups for their potential effect on the logP of a compound.

The pH dependence of the solubility of small molecules can be addressedin this method by measuring the contact angles of solutions at differentpHs. The parameter equivalent to logP in this case is logD, where D isthe distribution coefficient, defined as the ratio of the sum of theconcentrations of all species of the compound in octanol to the sum ofthe concentrations of all species of the compound in water at variouspHs. Contact angles measured at different pHs therefore offer thepossibility of an equivalent measure to logD.

It will also be useful to screen candidate compounds for their capacityto be actively transported across cell membranes and cells, or for theirresistance to such transport. For example, it is well known thatpharmaceutically useful anti-cancer molecules may be limited in theireffectiveness due to active transport out of target tumor cells.Similarly, monolayers of brain capillary endothelial cells have beenobserved to unidirectionally transport vincristine from basal side toapical side, effectively preventing the anti-cancer agent from enteringthe central nervous system. In some instances, chemical groups of valuewill, in addition to reducing non-specific protein binding, improvepharmcokinetics by enhancing passive or active transport towards theirsite of action, and/or inhibiting transport from the site of action.

The brain is one of the most difficult tissues for small molecules topenetrate. The neurovascular junctions are tight and contain very fewactive transporters that are mostly responsible for clearing smallmolecules out of the brain. The paracellular route (between celljunctions) is not available to small molecules, but only thetranscellular route is (through cell membranes). Classically, moleculesto target the brain, such as benzodiazepines, are hydrophobic to allowthem to penetrate cell membranes. The instant invention is compatiblewith the search for chemical groups that confer protein resistant andalleviate the common problem of excessive protein binding associatedwith molecules such as the benzodiazepines; this requires high dosing toaccount for the large percentage of binding to serum proteins. Theapproaches described earlier for the identification of binders of PGPwill be of help to optimize molecules for improved residence time in thebrain.

Several model systems are available, employing monolayers of variouscell types, for evaluation of active transport of pharmaceuticallyactive substances. For example, monolayers of Caco-2 intestinalepithelial cells can be used to evaluate active transport of substancesbetween the intestine and the bloodstream. When plated on a surfacewhich allows the flow of material from apical to basolateral and viceversa, such cells form a biological membrane which can be used tosimulate physiological absorption and bio-availability. In anotherexample, mouse brain capillary endothelial cell (MBEC) lines have beenestablished to evaluate active transport in and out of the centralnervous system. Another example of such cells is HT29 human coloncarcinoma cells. Further, monolayers expressing particular transporterproteins can be established using transfected cells. For example, Sasakiet al (2002) J. Biol. Chem. 8:6497 used a double-transfected Madin-Darbycanine kidney cell monolayer to study transport of organic anions.

Alternatives to cell monolayers may of course be utilized to examinepermeability. Alternatives typically comprise a biological structurecapable of active transport and include, but are not limited to, organsof the digestive tract obtained from lab animals and reconstitutedorgans or membranes created in vitro from cells seeded in an artificialmatrix.

In another aspect, the present invention provides a compound of thegeneral formula I, wherein the compound is an inhibitor of Rho-kinase.Rho kinase (ROCK), a serine/threonine kinase, serves as a target proteinfor small GTP-binding protein Rho. It serves as an important mediator ofnumerous cellular functions, including focal adhesions, motility, smoothmuscle contraction, and cytokinesis. In smooth muscle, ROCK plays animportant role in Ca²⁺ sensitization and the control of vascular tone.It modulates the level of phosphorylation of the myosin II light chainof myosin II, mainly through inhibition of myosin phosphatase, andcontributes to agonist-induced Ca²⁺ sensitization in smooth musclecontraction.

Rho kinase is found in two forms, ROCK 1 (ROCKβ; p160-ROCK) and ROCK 2(ROCKα). Since for example a ROCK-mediated pathway plays an importantrole in vascular smooth muscle contraction, cell adhesion, and cellmotility, it has gained importance in the pathogenesis ofatherosclerosis. ROCK inhibitors are shown to suppress coronary arteryspasms. A long-term inhibition of ROCK is reported to block thedevelopment of coronary arteriosclerotic lesions.

ROCK mediated pathways mediate numerous different cellular functions andROCK inhibitors can be useful in treatments of patients in need thereofsuffering from cardiovascular diseases such as hypertension,atherosclerosis, restenosis, cardiac hypertrophy, ocular hypertension,cerebral ischemia, cerebral vasospasm, penile erectile dysfunction,central nervous system disorders such as neuronal degeneration andspinal cord injury, and in neoplasias where inhibition of Rho-kinase hasbeen shown to inhibit tumor cell growth and metastasis, angiogenesis,arterial thrombotic disorders such as platelet aggregation and leukocyteaggregation, asthma, regulation of intraoccular pressure, and boneresorption. Such treatment often relies on administering a therapeuticagent to a patient, wherein the therapeutic agent has a high specificityfor a particular pathway or enzyme which is in need of regulation in thepatient, by the therapeutic agent such as an enzyme inhibitor. In oneaspect of the present invention there is provided, a compound which isan ihibitor of a Rho kinase (ROCK), preferably the compound of thepresent invention is an inhibitor of ROCK2.

Methods of determining kinase inhibition are well known in the art. Forexample, kinase activity of an enzyme and the inhibitory capacity of atest compound can be determined by measuring enzyme specificphosphorylation of a substrate. Commercial assays and kits can beemployed. For example, kinase inhibition can be determined using anIMAP® assay (Molecular Devices). This assay method involves the use of afluorescently-tagged peptide substrate. Phosphorylation of the taggedpeptide by a kinase of interest promotes binding of the peptide to atrivalent metal-based nanoparticle via the specific, high affinityinteraction between the phospho-group and the trivalent metal. Proximityto the nanoparticle results in increased fluorescence polarizationInhibition of the kinase by a kinase inhibitor prevents phosphorylationof the substrate and thereby limits binding of the fluorescently-taggedsubstrate to the nanoparticle. Such an assay can be compatible with amicrowell assay format, allowing simultaneous determination of IC₅₀ ofmultiple compounds.

In another aspect of the present invention there is provided a method oftreating a patient suffering from a disease comprising administering toa patient in need of such treatment a therapeutically effecitive amountof a compound of the present invention, wherein the disease iscardiovascular diseases such as hypertension, atherosclerosis,restenosis, cardiac hypertrophy, ocular hypertension, cerebral ischemia,cerebral vasospasm, penile erectile dysfunction, central nervous systemdisorders such as neuronal degeneration and spinal cord injury, and inneoplasias where inhibition of Rho-kinase has been shown to inhibittumor cell growth and metastasis, angiogenesis, arterial thromboticdisorders such as platelet aggregation and leukocyte aggregation,asthma, regulation of intraoccular pressure, and bone resorption.

In solid dosage forms of the invention for oral administration(capsules, tablets, pills, dragees, powders, granules, trouches and thelike), the active ingredient is mixed with one or morepharmaceutically-acceptable carriers, such as sodium citrate ordicalcium phosphate, and/or any of the following: (1) fillers orextenders, such as starches, lactose, sucrose, glucose, mannitol, and/orsilicic acid; (2) binders, such as, for example, carboxymethylcellulose,alginates, gelatin, polyvinyl pyrrolidone, sucrose and/or acacia; (3)humectants, such as glycerol; (4) disintegrating agents, such asagar-agar, calcium carbonate, potato or tapioca starch, alginic acid,certain silicates, and sodium carbonate; (5) solution retarding agents,such as paraffin; (6) absorption accelerators, such as quaternaryammonium compounds and surfactants, such as poloxamer and sodium laurylsulfate; (7) wetting agents, such as, for example, cetyl alcohol,glycerol monostearate, and non-ionic surfactants; (8) absorbents, suchas kaolin and bentonite clay; (9) lubricants, such as talc, calciumstearate, magnesium stearate, solid polyethylene glycols, sodium laurylsulfate, zinc stearate, sodium stearate, stearic acid, and mixturesthereof; (10) coloring agents; and (11) controlled release agents suchas crospovidone or ethyl cellulose. In the case of capsules, tablets andpills, the pharmaceutical compositions may also comprise bufferingagents. Solid compositions of a similar type may also be employed asfillers in soft and hard-shelled gelatin capsules using such excipientsas lactose or milk sugars, as well as high molecular weight polyethyleneglycols and the like.

A tablet may be made by compression or molding, optionally with one ormore accessory ingredients. Compressed tablets may be prepared usingbinder (for example, gelatin or hydroxypropylmethyl cellulose),lubricant, inert diluent, preservative, disintegrant (for example,sodium starch glycolate or cross-linked sodium carboxymethyl cellulose),surface-active or dispersing agent. Molded tablets may be made bymolding in a suitable machine a mixture of the powdered compoundmoistened with an inert liquid diluent.

The tablets, and other solid dosage forms of the pharmaceuticalcompositions of the present invention, such as dragees, capsules, pillsand granules, may optionally be scored or prepared with coatings andshells, such as enteric coatings and other coatings well known in thepharmaceutical-formulating art. They may also be formulated so as toprovide slow or controlled release of the active ingredient thereinusing, for example, hydroxypropylmethyl cellulose in varying proportionsto provide the desired release profile, other polymer matrices,liposomes and/or microspheres. They may be formulated for rapid release,e.g., freeze-dried. They may be sterilized by, for example, filtrationthrough a bacteria-retaining filter, or by incorporating sterilizingagents in the form of sterile solid compositions which can be dissolvedin sterile water, or some other sterile injectable medium immediatelybefore use. These compositions may also optionally contain opacifyingagents and may be of a composition that they release the activeingredient(s) only, or preferentially, in a certain portion of thegastrointestinal tract, optionally, in a delayed manner. Examples ofembedding compositions which can be used include polymeric substancesand waxes. The active ingredient can also be in micro-encapsulated form,if appropriate, with one or more of the above-described excipients.

Liquid dosage forms for oral administration of the compounds of theinvention include pharmaceutically acceptable emulsions, microemulsions,solutions, suspensions, syrups and elixirs. In addition to the activeingredient, the liquid dosage forms may contain inert diluents commonlyused in the art, such as, for example, water or other solvents,solubilizing agents and emulsifiers, such as ethyl alcohol, isopropylalcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzylbenzoate, propylene glycol, 1,3-butylene glycol, oils (in particular,cottonseed, groundnut, corn, germ, olive, castor and sesame oils),glycerol, tetrahydrofuryl alcohol, polyethylene glycols and fatty acidesters of sorbitan, and mixtures thereof.

Besides inert diluents, the oral compositions can also include adjuvantssuch as wetting agents, emulsifying and suspending agents, sweetening,flavoring, coloring, perfuming and preservative agents.

Suspensions, in addition to the active compounds, may contain suspendingagents as, for example, ethoxylated isostearyl alcohols, polyoxyethylenesorbitol and sorbitan esters, microcrystalline cellulose, aluminummetahydroxide, bentonite, agar-agar and tragacanth, and mixturesthereof.

Formulations of the pharmaceutical compositions of the invention forrectal or vaginal administration may be presented as a suppository,which may be prepared by mixing one or more compounds of the inventionwith one or more suitable nonirritating excipients or carrierscomprising, for example, cocoa butter, polyethylene glycol, asuppository wax or a salicylate, and which is solid at room temperature,but liquid at body temperature and, therefore, will melt in the rectumor vaginal cavity and release the active compound.

Formulations of the present invention which are suitable for vaginaladministration also include pessaries, tampons, creams, gels, pastes,foams or spray formulations containing such carriers as are known in theart to be appropriate.

Dosage forms for the topical or transdermal administration of a compoundof this invention include powders, sprays, ointments, pastes, creams,lotions, gels, solutions, patches and inhalants. The active compound maybe mixed under sterile conditions with a pharmaceutically-acceptablecarrier, and with any preservatives, buffers, or propellants which maybe required.

The ointments, pastes, creams and gels may contain, in addition to anactive compound of this invention, excipients, such as animal andvegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulosederivatives, polyethylene glycols, silicones, bentonites, silicic acid,talc and zinc oxide, or mixtures thereof.

Powders and sprays can contain, in addition to a compound of thisinvention, excipients such as lactose, talc, silicic acid, aluminumhydroxide, calcium silicates and polyamide powder, or mixtures of thesesubstances. Sprays can additionally contain customary propellants, suchas chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons,such as butane and propane.

Transdermal patches have the added advantage of providing controlleddelivery of a compound of the present invention to the body. Such dosageforms can be made by dissolving or dispersing the compound in the propermedium. Absorption enhancers can also be used to increase the flux ofthe compound across the skin. The rate of such flux can be controlled byeither providing a rate controlling membrane or dispersing the compoundin a polymer matrix or gel.

Ophthalmic formulations, eye ointments, powders, solutions and the like,are also contemplated as being within the scope of this invention.

Pharmaceutical compositions of this invention suitable for parenteraladministration comprise one or more compounds of the invention incombination with one or more pharmaceutically-acceptable sterileisotonic aqueous or nonaqueous solutions, dispersions, suspensions oremulsions, or sterile powders which may be reconstituted into sterileinjectable solutions or dispersions just prior to use, which may containsugars, alcohols, antioxidants, buffers, bacteriostats, solutes whichrender the formulation isotonic with the blood of the intended recipientor suspending or thickening agents.

Examples of suitable aqueous and nonaqueous carriers which may beemployed in the pharmaceutical compositions of the invention includewater, ethanol, polyols (such as glycerol, propylene glycol,polyethylene glycol, and the like), and suitable mixtures thereof,vegetable oils, such as olive oil, and injectable organic esters, suchas ethyl oleate. Proper fluidity can be maintained, for example, by theuse of coating materials, such as lecithin, by the maintenance of therequired particle size in the case of dispersions, and by the use ofsurfactants.

These compositions may also contain adjuvants such as preservatives,wetting agents, emulsifying agents and dispersing agents. Prevention ofthe action of microorganisms upon the subject compounds may be ensuredby the inclusion of various antibacterial and antifungal agents, forexample, paraben, chlorobutanol, phenol sorbic acid, and the like. Itmay also be desirable to include isotonic agents, such as sugars, sodiumchloride, and the like into the compositions. In addition, prolongedabsorption of the injectable pharmaceutical form may be brought about bythe inclusion of agents which delay absorption such as aluminummonostearate and gelatin.

In some cases, in order to prolong the effect of a drug, it is desirableto slow the absorption of the drug from subcutaneous or intramuscularinjection. This may be accomplished by the use of a liquid suspension ofcrystalline or amorphous material having poor water solubility. The rateof absorption of the drug then depends upon its rate of dissolutionwhich, in turn, may depend upon crystal size and crystalline form.Alternatively, delayed absorption of a parenterally-administered drugform is accomplished by dissolving or suspending the drug in an oilvehicle.

Injectable depot forms are made by forming microencapsule matrices ofthe subject compounds in biodegradable polymers such aspolylactide-polyglycolide. Depending on the ratio of drug to polymer,and the nature of the particular polymer employed, the rate of drugrelease can be controlled. Examples of other biodegradable polymersinclude poly(orthoesters) and poly(anhydrides). Depot injectableformulations are also prepared by entrapping the drug in liposomes ormicroemulsions which are compatible with body tissue.

When the compounds of the present invention are administered aspharmaceuticals, to humans and animals, they can be given per se or as apharmaceutical composition containing, for example, 0.1 to 99% (morepreferably, 10 to 30%) of active ingredient in combination with apharmaceutically acceptable carrier.

The preparations of the present invention may be given orally,parenterally, topically, or rectally. They are of course given in formssuitable for each administration route. For example, they areadministered in tablets or capsule form, by injection, inhalation, eyelotion, ointment, suppository, etc. administration by injection,infusion or inhalation; topical by lotion or ointment; and rectal bysuppositories. Oral administrations are preferred.

The phrases “parenteral administration” and “administered parenterally”as used herein means modes of administration other than enteral andtopical administration, usually by injection, and includes, withoutlimitation, intravenous, intramuscular, intraarterial, intrathecal,intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal,transtracheal, subcutaneous, subcuticular, intraarticulare, subcapsular,subarachnoid, intraspinal and intrasternal injection and infusion.

The phrases “systemic administration,” “administered systemically,”“peripheral administration” and “administered peripherally” as usedherein mean the administration of a compound, drug or other materialother than directly into the central nervous system, such that it entersthe patient's system and, thus, is subject to metabolism and other likeprocesses, for example, subcutaneous administration.

These compounds may be administered to humans and other animals fortherapy by any suitable route of administration, including orally,nasally, as by, for example, a spray, rectally, intravaginally,parenterally, intracisternally and topically, as by powders, ointmentsor drops, including buccally and sublingually.

Regardless of the route of administration selected, the compounds of thepresent invention, which may be used in a suitable hydrated form, and/orthe pharmaceutical compositions of the present invention, are formulatedinto pharmaceutically-acceptable dosage forms by conventional methodsknown to those of skill in the art.

Actual dosage levels of the active ingredients in the pharmaceuticalcompositions of this invention may be varied so as to obtain an amountof the active ingredient which is effective to achieve the desiredtherapeutic response for a particular patient, composition, and mode ofadministration, without being toxic to the patient.

The selected dosage level will depend upon a variety of factorsincluding the activity of the particular compound of the presentinvention employed, or the ester, salt or amide thereof, the route ofadministration, the time of administration, the rate of excretion ormetabolism of the particular compound being employed, the rate andextent of absorption, the duration of the treatment, other drugs,compounds and/or materials used in combination with the particularcompound employed, the age, sex, weight, condition, general health andprior medical history of the patient being treated, and like factorswell known in the medical arts.

A physician or veterinarian having ordinary skill in the art can readilydetermine and prescribe the effective amount of the pharmaceuticalcomposition required. For example, the physician or veterinarian couldstart doses of the compounds of the invention employed in thepharmaceutical composition at levels lower than that required in orderto achieve the desired therapeutic effect and gradually increase thedosage until the desired effect is achieved.

In general, a suitable daily dose of a compound of the invention will bethat amount of the compound which is the lowest dose effective toproduce a therapeutic effect. Such an effective dose will generallydepend upon the factors described above. Generally, oral, intravenous,intracerebroventricular and subcutaneous doses of the compounds of thisinvention for a patient, when used for the indicated analgesic effects,will range from about 0.0001 to about 100 mg per kilogram of body weightper day.

If desired, the effective daily dose of the active compound may beadministered as two, three, four, five, six or more sub-dosesadministered separately at appropriate intervals throughout the day,optionally, in unit dosage forms. Preferred dosing is one administrationper day.

While it is possible for a compound of the present invention to beadministered alone, it is preferable to administer the compound as apharmaceutical formulation (composition).

The compounds according to the invention may be formulated foradministration in any convenient way for use in human or veterinarymedicine, by analogy with other pharmaceuticals.

In another aspect, the present invention provides pharmaceuticallyacceptable compositions which comprise a therapeutically-effectiveamount of one or more of the subject compounds, as described above,formulated together with one or more pharmaceutically acceptablecarriers (additives) and/or diluents. As described in detail below, thepharmaceutical compositions of the present invention may be speciallyformulated for administration in solid or liquid form, including thoseadapted for the following: (1) oral administration, for example,drenches (aqueous or non-aqueous solutions or suspensions), tablets,boluses, powders, granules, pastes for application to the tongue; (2)parenteral administration, for example, by subcutaneous, intramuscularor intravenous injection as, for example, a sterile solution orsuspension; (3) topical application, for example, as a cream, ointmentor spray applied to the skin, lungs, or mucous membranes; or (4)intravaginally or intrarectally, for example, as a pessary, cream orfoam; (5) sublingually or buccally; (6) ocularly; (7) transdermally; or(8) nasally.

The term “treatment” is intended to encompass also prophylaxis, therapyand cure.

The patient receiving this treatment is any animal in need, includingprimates, in particular humans, and other mammals such as equines,cattle, swine and sheep; and poultry and pets in general.

The compound of the invention can be administered as such or inadmixtures with pharmaceutically acceptable carriers and can also beadministered in conjunction with antimicrobial agents such aspenicillins, cephalosporins, aminoglycosides and glycopeptides.Conjunctive therapy, thus includes sequential, simultaneous and separateadministration of the active compound in a way that the therapeuticaleffects of the first administered one is not entirely disappeared whenthe subsequent is administered.

The addition of the active compound of the invention to animal feed ispreferably accomplished by preparing an appropriate feed premixcontaining the active compound in an effective amount and incorporatingthe premix into the complete ration.

Alternatively, an intermediate concentrate or feed supplement containingthe active ingredient can be blended into the feed. The way in whichsuch feed premixes and complete rations can be prepared and administeredare described in reference books (such as “Applied Animal Nutrition”,W.H. Freedman and CO., San Francisco, U.S.A., 1969 or “Livestock Feedsand Feeding” 0 and B books, Corvallis, Ore., U.S.A., 1977).

Recently, the pharmaceutical industry introduced microemulsificationtechnology to improve bioavailability of some lipophilic (waterinsoluble) pharmaceutical agents. Examples include Trimetrine (Dordunoo,S. K., et al., Drug Development and Industrial Pharmacy, 17(12),1685-1713, 1991 and REV 5901 (Sheen, P. C., et al., J Pharm Sci 80(7),712-714, 1991). Among other things, microemulsification providesenhanced bioavailability by preferentially directing absorption to thelymphatic system instead of the circulatory system, which therebybypasses the liver, and prevents destruction of the compounds in thehepatobiliary circulation.

In one aspect of invention, the formulations contain micelles formedfrom a compound of the present invention and at least one amphiphiliccarrier, in which the micelles have an average diameter of less thanabout 100 nm. More preferred embodiments provide micelles having anaverage diameter less than about 50 nm, and even more preferredembodiments provide micelles having an average diameter less than about30 nm, or even less than about 20 nm.

While all suitable amphiphilic carriers are contemplated, the presentlypreferred carriers are generally those that haveGenerally-Recognized-as-Safe (GRAS) status, and that can both solubilizethe compound of the present invention and microemulsify it at a laterstage when the solution comes into a contact with a complex water phase(such as one found in human gastro-intestinal tract). Usually,amphiphilic ingredients that satisfy these requirements have HLB(hydrophilic to lipophilic balance) values of 2-20, and their structurescontain straight chain aliphatic radicals in the range of C-6 to C-20.Examples are polyethylene-glycolized fatty glycerides and polyethyleneglycols.

Particularly preferred amphiphilic carriers are saturated andmonounsaturated polyethyleneglycolyzed fatty acid glycerides, such asthose obtained from fully or partially hydrogenated various vegetableoils. Such oils may advantageously consist of tri-, di- and mono-fattyacid glycerides and di- and mono-polyethyleneglycol esters of thecorresponding fatty acids, with a particularly preferred fatty acidcomposition including capric acid 4-10, capric acid 3-9, lauric acid40-50, myristic acid 14-24, palmitic acid 4-14 and stearic acid 5-15%.Another useful class of amphiphilic carriers includes partiallyesterified sorbitan and/or sorbitol, with saturated or mono-unsaturatedfatty acids (SPAN-series) or corresponding ethoxylated analogs(TWEEN-series).

Commercially available amphiphilic carriers are particularlycontemplated, including Gelucire-series, Labrafil, Labrasol, orLauroglycol (all manufactured and distributed by Gattefosse Corporation,Saint Priest, France), PEG-mono-oleate, PEG-di-oleate, PEG-mono-laurateand di-laurate, Lecithin, Polysorbate 80, etc (produced and distributedby a number of companies in USA and worldwide).

Hydrophilic polymers suitable for use in the present invention are thosewhich are readily water-soluble, can be covalently attached to avesicle-forming lipid, and which are tolerated in vivo without toxiceffects (i.e., are biocompatible). Suitable polymers includepolyethylene glycol (PEG), polylactic (also termed polylactide),polyglycolic acid (also termed polyglycolide), a polylactic-polyglycolicacid copolymer, and polyvinyl alcohol. Preferred polymers are thosehaving a molecular weight of from about 100 or 120 daltons up to about5,000 or 10,000 daltons, and more preferably from about 300 daltons toabout 5,000 daltons. In a particularly preferred embodiment, the polymeris polyethyleneglycol having a molecular weight of from about 100 toabout 5,000 daltons, and more preferably having a molecular weight offrom about 300 to about 5,000 daltons. In a particularly preferredembodiment, the polymer is polyethyleneglycol of 750 daltons (PEG(750)).The polymers used in the present invention have a significantly smallermolecular weight, approximately 100 daltons, compared to the large MW of5000 daltons or greater that used in standard pegylation techniques.Polymers may also be defined by the number of monomers therein; apreferred embodiment of the present invention utilizes polymers of atleast about three monomers, such PEG polymers consisting of threemonomers (approximately 150 daltons).

Other hydrophilic polymers which may be suitable for use in the presentinvention include polyvinylpyrrolidone, polymethoxazoline,polyethyloxazoline, polyhydroxypropyl methacrylamide,polymethacrylamide, polydimethylacrylamide, and derivatized cellulosessuch as hydroxymethylcellulose or hydroxyethylcellulose.

In certain embodiments, a formulation of the present invention comprisesa biocompatible polymer selected from the group consisting ofpolyamides, polycarbonates, polyalkylenes, polymers of acrylic andmethacrylic esters, polyvinyl polymers, polyglycolides, polysiloxanes,polyurethanes and co-polymers thereof, celluloses, polypropylene,polyethylenes, polystyrene, polymers of lactic acid and glycolic acid,polyanhydrides, poly(ortho)esters, poly(butic acid), poly(valeric acid),poly(lactide-co-caprolactone), polysaccharides, proteins, polyhyaluronicacids, polycyanoacrylates, and blends, mixtures, or copolymers thereof.

The release characteristics of a formulation of the present inventiondepend on the encapsulating material, the concentration of encapsulateddrug, and the presence of release modifiers. For example, release can bemanipulated to be pH dependent, for example, using a pH sensitivecoating that releases only at a low pH, as in the stomach, or a higherpH, as in the intestine. An enteric coating can be used to preventrelease from occurring until after passage through the stomach. Multiplecoatings or mixtures of cyanamide encapsulated in different materialscan be used to obtain an initial release in the stomach, followed bylater release in the intestine. Release can also be manipulated byinclusion of salts or pore forming agents, which can increase wateruptake or release of drug by diffusion from the capsule. Excipientswhich modify the solubility of the drug can also be used to control therelease rate. Agents which enhance degradation of the matrix or releasefrom the matrix can also be incorporated. They can be added to the drug,added as a separate phase (i.e., as particulates), or can beco-dissolved in the polymer phase depending on the compound. In allcases the amount should be between 0.1 and thirty percent (w/w polymer).Types of degradation enhancers include inorganic salts such as ammoniumsulfate and ammonium chloride, organic acids such as citric acid,benzoic acid, and ascorbic acid, inorganic bases such as sodiumcarbonate, potassium carbonate, calcium carbonate, zinc carbonate, andzinc hydroxide, and organic bases such as protamine sulfate, spermine,choline, ethanolamine, diethanolamine, and triethanolamine andsurfactants such as Tween® and Pluronic®. Pore forming agents which addmicrostructure to the matrices (i.e., water soluble compounds such asinorganic salts and sugars) are added as particulates. The range shouldbe between one and thirty percent (w/w polymer).

Uptake can also be manipulated by altering residence time of theparticles in the gut. This can be achieved, for example, by coating theparticle with, or selecting as the encapsulating material, a mucosaladhesive polymer. Examples include most polymers with free carboxylgroups, such as chitosan, celluloses, and especially polyacrylates (asused herein, polyacrylates refers to polymers including acrylate groupsand modified acrylate groups such as cyanoacrylates and methacrylates).

1. ROCK Binding Assay

ROCK-II inhibitory activity can be measured using the ROCK-II Assay Kit(Molecular Devices, inc.; Sunnyvale, Calif.).

2. A Functional Measure of ROCK Activity in Cells

MLC Phosphorylation

Myosin regulatory light chain phosphorylation can be measures invascular smooth muscle (VSM) cells. VSM cells are isolated from thepulmonary artery of newborn calves and used in the 2nd to 4th passage.Cells are maintained in low glucose DME (JRH Biosciences) supplementedwith 2 mM glutamine, 100 U/ml penicillin 100 U/ml streptomycin, 10 mMHepes (Life Technologies), and 10% fetal bovine serum (Hyclone) in 10%CO₂. Confluent monolayers are serum-starved for 72 hours in DMEcontaining 0.4% fetal bovine serum prior to experiments. Quiescent cellmonolayers are dissociated into single cells and plated at low. Forexperimental manipulation, cells are plated in DME containing 1% bovineserum albumin, transferrin (5 μg/ml; Collaborative Research), human highdensity lipoprotein (10 μg/ml; Intracel), 20 mM Hepes, sodium pyruvate(110 mg/L), penicillin G (100 units/ml), streptomycin (100 μg/ml) andL-glutamine (0.292 mg/ml). Cells are harvested in ice-cold 10%trichloroacetic acid supplemented with 10 mM dithiothreitol (Sigma) andcentrifuged at 13,000 rpm for 15 minutes at 4° C. The pellets are washedonce with ice cold distilled water, and once with cold acetone. Samplesare then placed in sample buffer (10 M urea [#161-0730, Bio-Rad], 1×Tris-glycine running buffer, 150 mM dithiothreitol, 0.01% bromophenolblue), soniccated, loaded onto and run on electrophoretic gels at 6 mA.Proteins are transferred to nitrocellulose in 1× Tris/glycine bufferwith 20% methanol, blocked in three percent bovine serum albumin in TrisBuffered Saline, and probed with antibodies to detect phosphorylatedisoforms of myosin regulatory light chain (Cell Signaling Technologies)for two hours at room temperature. Signals are detected using ahorseradish peroxidase-conjugated secondary antibody (NA-131, Amersham;1:4000) and Renaissance Enhanced Luminol Reagent (NEN Life SciencesProducts) as a chemiluminescent substrate. Signal intensity isnormalized and analyzed using NIH Image.

Motility

Cellular motility can be assessed using a migration assay.Fluorescently-labeled HT1080 human fibrosarcoma cells are seeded into aFluoroblok Transwell 8 μM pore 96-well plate (Becton Dickenson) at adensity of 40,000 cells per well in serum-free, phenol-free MEM.Compounds are added to the cells in the transwell inserts at a finalconcentration of 0.5% dimethylsulfoxide. Compounds are also added to thebottom wells in phenol-free MEM containing 10% fetal bovine serum as thechemoattractant. Cells are incubated at 37° C. for 4 h, and fluorescenceis measured from the bottom of the plate on a fluorescent plate reader(Analyst, LJL Biosystems).
